| abstract |
A membrane for water treatment which comprises a porous membrane of a vinylidene fluoride resin comprising 100 parts by weight of a vinylidene fluoride resin and 0.01-5 parts by weight of photocatalytic titanium oxide evenly dispersed therein. The water treatment membrane can eliminate problems accompanying the hydrophobic nature of the porous vinylidene fluoride membrane while taking advantage of excellent properties of the membrane, such as mechanical properties, weatherability, and chemical resistance. |
